| Abstract:
This paper exhibits an instrumented flexible wing mockup demonstrating a wing shape estimation technique for automatic structural/flight control of very flexible aircraft undergoing large and geometrically nonlinear wing deflections. The proposed method exploits data fusion, using an extended Kalman filter, between distributed rate gyros across the wing and a sighting device at the wing root, and does not require knowledge of strain-displacement curves or specific aircraft dynamic models. The experiment is conducted in a motion capture room for ground truth availability and shows, as predicted in previous work, that the resulting estimation errors are bounded and have promising frequency response.
